    round robin setting in esxi 6.5

    jprovine7 Enthusiast

      I the past on esxi 5.5 I have had to manually set round robin for the connection to my pure all flash array. Does that have to be done in esxi 6.5 and how can I verify that my setting are correct? These are two settings I have configured in the past iops and round robin

       

      esxcli storage nmp satp rule add -s "VMW_SATP_ALUA" -V "PURE" -M "FlashArray" -P "VMW_PSP_RR" -O "iops=1

       

       

      esxcli storage nmp psp roundrobin deviceconfig set -d naa.<naa. adress> -I 1 -t iops

          Please check the below articles. These are applicable to 6.5 as well -

           

          Change the default PSP - https://kb.vmware.com/s/article/1017760

           

          Change the IOPS from 1000 to 1 - https://kb.vmware.com/s/article/2069356

            I will check these out I assume that they have instruction on how to verify the setting

              Nope, they have instructions on how to change the settings as well.

                so they don't have a way to verify the settings?

                  If you open the above articles, you will definitely get your answers. Anyways, below is how you verify the current configured PSP and IOPS value set respectively -

                   

                  Check the set PSP - <esxcli storage nmp satp list>

                   

                  Check the IOPS value - <esxcli storage nmp device list> --> Navigate to the respective LUN and check for the row starting with 'Path Selection Policy Device Config'

                   

                  Cheers,

                    This was easy it appears it was already set in esxi 6.5, which is my real question is it set by default in esxi 6.5, because in the past I had to go and change the setting for esxi 6.5. Now to go look at the setting for PSP

                     

                    Path Selection Policy Device Config: {policy=rr,iops=1

                      I did this for the PSP but I did not see in the article where is says what its suppose to be for 6.5

                        As per my understanding, it selects the default PSP based on the SATP.
